WILLIAM COOPER, OF MOUNT GILEAD, OHIO.

DIRT-LOADING APPARATUS FOR EXCAVATORS.

Specification of Letters Patent No. 27,699, dated April 3, 1860.

To all whom it may concern:

Be it known that I, WILLIAM COOPER, of Mount Gilead, in the county ofMorrow and State of Ohio, have invented certain new and usefulImprovements in Machines for Loading Dirt into Vagons and Carts &c., orfor Ditching and Throwing Up Roads; and I do hereby declare that thefollowing is a full, clea'r, and exact description of the same,reference being had to the accompanying drawings and to the letters ofreference marked thereon.

The nature of my invention consists in arranging those parts of themachine which will be particularly described, substantially as will beset forth.

In the annexed drawings Figure l represents a side elevation. Fig. 2.represents a plan view.

In the figures A represents a beam to the forwai'd end of which issecured a plow B, and trough C. The plow is provided with two land sidesone of which is secured to the beam, and the other, to one .side of thetrough C, as is seen in Fig. 2. The rear end of the beam is sustained byan axle D, which passes through, and is supported by two wheels I?, F.

Il, represents a bar, one end of which rests upon the axle, D. This barruns parallel #ith the beam, but is shorter and is connectcd at itsforward end with the beam by means of a cross bar H. Upon the beam andthe bar, I-I, are erected four standards, (two on each,) which support aframe, in which a shaft, a, has its bearings. This shaft lies across theframe and is made square with the exception of its journals, and thewidth of a pulley (which slides over it,) at its center. These parts aremade round.

c, represents a sliding pulley which passes over the shaft a, saidpulley being provided with a square hole through it, made of such sizeas to lit snugly over the shaft A band, Ii, passes around a pulley onthe axle I), and over the pulley c, for the purpose of communicatingmotion to said pulley c.

ai, represents' a pulley near the forward end of the trough C. Band E,passes around pulley fo, and-then around pulley c, forming a continuousbelt, the upper side of which is supported by means of a series ofrollers, ml m// ne trough t., is inclined as is shown its lower endbeing secured to the plow B, and its upper end resting over the pulleyc. The belt or band E, forms the bottom of this trough, and when themachine is set in motion, the band travels backward, and thus conveysthe dirt or earth from the plow up the trough and elevates it at theback of the machine to be dropped into a cart or wagon placed to receiveit.

I do notcontend that carrying the dirt or earth back by means of a beltis new, but it will be seen that the pulley c, over which the rear ofthe band passes, is made to slide to one side or the other of the shafta, as' it may be desired, for the purpose of emptying the earth to oneside or the other of the machine.

The trough moves with the pulley c, at its rear end, and may be made toempty the earth into carts or wagons, or it may be made to empty it toone side of the ditch which the plow may be making.

The sliding pulley o, when used in connection with the trough, band, andplow, for the purpose of directing the discharge of the earthconstitutes the principal feature of my invention. I am aware that thedirt, etc. has been carried ofi1 and emptied in other ways, but these Idisclaim, confining myself to the particular' manner herein shown.

Having thus fully described by invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the square shaft a, with the sliding pulley, c,trough C, band E, pulley m, and plow B, the several parts being arrangedtogether substantially in the manner and for the purpose specified.

IVM. COOPER.
